ok i got my 8n 6 volt running but the fan and water pump pulley are not turning,how bad is it ?? please tell me my crank shaft is not broken , thank you for ant help
 
Loosen up the fan belt and try turning the fan. It should spin easily if you have the belt really loose. If not, take the belt clear off. I suspect a bearing in the water pump is frozen and you need a new or rebuilt water pump.
 
Pull the pump & find out why it's spinning. Plan on getting the pump rebuilt.

Yes, you can pull the pump w/o removing the hood.....but I've never done it & don't plan on trying!

when the engine is running the bottom pulley does not turn is there a key-way or something,it only turns by turning the fan
 
no the crank shaft pulley is not turning,tractor was running,the pulleys will turn if i turn the fan by hand,is there a keyway on the crank pulley?
 
When you removed the loader did you
unbolt the drive coupling and then
forget to put the 4 bolts back in that
hold the pulley on? I'm assuming it's
simular to the naa and later ones, never
actually looked close at an N crank

On the N-series the pulley is keyed to the crankshaft. If it isn't turning the key is sheared or the pulley is not engaging the key. Lot's of screw ups in this area from people trying to install or remove a loader pump drive...
